We report a comprehensive study on gated and optically doped samples by magnetooptical spectroscopy in the THz range. The quasi-classical analysis of the cyclotron resonance allowed the mapping of the band dispersion of Dirac charge carriers in a broad range of electron and hole doping. A smooth transition through the charge neutrality point between Dirac holes and electrons was observed. An additional peak coming from a second type of holes with an almost density-independent mass of around 0.04m0 was detected in the hole-doping range and attributed to an asymmetric spin splitting of the Dirac cone. Spectroscopic evidence for disorder-induced band energy fluctuations could not be detected in present cyclotron resonance experiments.","lang":"eng"}],"date_published":"2022-07-20T00:00:00Z","publication_status":"published","issue":"14","publisher":"MDPI","scopus_import":"1","oa":1,"oa_version":"Published Version","date_created":"2023-01-16T10:02:31Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Band structure near the Dirac Point in HgTe quantum wells with critical thickness","quality_controlled":"1","status":"public","external_id":{"isi":["000834401600001"]},"publication_identifier":{"issn":["2079-4991"]},"doi":"10.3390/nano12142492","has_accepted_license":"1","publication":"Nanomaterials","author":[{"last_name":"Shuvaev","first_name":"Alexey","full_name":"Shuvaev, Alexey"},{"full_name":"Dziom, Uladzislau","id":"6A9A37C2-8C5C-11E9-AE53-F2FDE5697425","first_name":"Uladzislau","last_name":"Dziom","orcid":"0000-0002-1648-0999"},{"full_name":"Gospodarič, Jan","last_name":"Gospodarič","first_name":"Jan"},{"full_name":"Novik, Elena G.","last_name":"Novik","first_name":"Elena G."},{"full_name":"Dobretsova, Alena A.","last_name":"Dobretsova","first_name":"Alena A."},{"full_name":"Mikhailov, Nikolay N.","last_name":"Mikhailov","first_name":"Nikolay N."},{"first_name":"Ze Don","last_name":"Kvon","full_name":"Kvon, Ze Don"},{"last_name":"Pimenov","first_name":"Andrei","full_name":"Pimenov, Andrei"}],"language":[{"iso":"eng"}],"_id":"12278","article_number":"2492","citation":{"ama":"Shuvaev A, Dziom U, Gospodarič J, et al.
